When objects remain in the same place, it is called...

• gravity
• friction
• balanced force
• unbalanced force

• true
• false

An unbalanced force is when objects move in one direction because the force is greater from that direction.

• true
• false

• kinetic energy
• acceleration
• deceleration

Inertia is....

• for every action, there is an equal and opposite reaction
• larger objects take more force to move 
• an object in motion tends to stay in motion unless acted on by an opposite force
• a push that acts in the opposite direction and it slows down.
